The Batman v Superman: Dawn of Justice trailer was clearly the star of the show at the Warner Bros Comic-Con panel on 11 July. However, the studio rolled out a big surprise in the form of a pretty awesome Suicide Squad trailer.

Footage from the upcoming supervillain team-up flick superbly teases the expansion of the DC Cinematic Universe - especially with regards to The Joker and Batman's storyline.

Batman v Superman: Dawn of Justice director Zack Snyder was also on-hand to discuss the film's importance to the growing DC Entertainment film universe. Check out the video below: (via ComicBook)

Meanwhile, as fans await the official release of the Suicide Squad trailer, a leaked version has already hit the web. So, in case you do not want to wait too long to see Deadshot, Harley Quinn and the maniacal Joker in action, you can check out the leaked trailer below, followed by a description of how it plays out:

Dinner table. "I have the worst of the worst", a man tells Amanda Waller. The DC Comics logo ticks into screen. Waller says she put them in a hole and threw away the hole. She references Superman. "A task force of the most dangerous people on the planet who can do some good." "We have built in deniability" because they're bad guys.

Harley Quinn hangs upside down in a cage. Deadshot beats a punching bag. Killer Croc strapped to a gurney. Harley asks, "Are you the devil?" Deadshot grapples down a building. A hospital gets shot up. Enchantress sits in a pool. Deadshot calls themselves the Suicide Squad as the team forms in the street. Helicopters fire. Harley holds her bat like a shotgun. The Joker walks down a hallway. Harley strangles a guard. Batman rides the Joker's car. Harley pops gum. Boomerang talks about crazy people. Joker's laugh! "I'm not gonna kill ya!" Joker says. The squad walks down the street. Joker goes on, "I'm just gonna hurt ya, really, really bad," with the most insane look anyone can ever have in their eyes. (via ComicBook)
